H. C. FREESE WINDOW SCREEN DRAIN Filed May 11, 1945 awe/whom [[Cfreese ///////#//A\\\M\\ v Patented Sept. 10, 1946 UNITED STATES PATENT OFFICE 3 Claims.

This present invention relates to a window screen drain which affords th rain or moisture forced through the screen an outlet to the exterior of the building and protects the wallpaper and floor under the window sills.

The main purpose of this invention is the construction of a window screen drain which is of simple design and necessitates but few changes in the ledge of the conventional window casing and the screen frame. The present-day wood screens have a fairly tight fit when installed and tend to swell almost watertight during a heavy rainfall. The bottom piece of a wood screen has no openings and its upper edge is considerably higher than the window sill with the result that the water collects in the space above the ledge and between the sill and screen during a heavy rain and drains over the sill into the house.

With these objects and others in view, as will become apparent in the course of the description, the invention resides in the novelty of features, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims.

The preferred embodiment of my invention is illustrated in the accompanying drawing, forming part of this application, in which:

Figur 1 is a fragmentary view of the lower portion of a window screen in which an embodiment of my invention is incorporated;

Figure 2 is a fragmentary cross-section through the lower portion of a window, the wall in which the window is arranged, and of the screen equipped with an embodiment of my invention;

Figure 3 is a vertical, transverse detail section of my window screen drain.

In the drawing in which like reference characters designate like or similar parts, numeral 2 denotes the wall of a house having a window opening in which a casing is arranged including a window ledge consisting of a'lower board 3 of a horizontal width exceeding the width of the wall and an upper board 4 of lesser width. The vertical inner end faces of these boards are flush with the inner surface of the wall and the vertical outer end face of the lower board lies in a plane disposed outwardly of the plane containing the outer vertical end face of the upper board. Thus the latter end face defines with the free or exposed upper surface of the lower board an angular shoulder 5 for a purpose which will become clear as the description proceeds.

Beneath the free lower surface of the lower ledge board extends a board 6 lying flat against the outer surface of the wall. To the inner surface of the wall is secured a board 7 the upper end face of which is flush with the inner end portion of the upper surface of the upper ledge board 4. This surface declines outwardly to facilitate the outward flow f rain.

Above the board 1 described is the window sill 8 which is horizontally disposed and extends inwardly and somewhat outwardly of th vertically disposed board 1. The vertical portions of the window casing have on their inner side a groove in which the window sash 9 containing the glass pane l0 can slide.

A screen sash ll, preferably ofwood or other suitable material, has dimensions similar to those of the glass sash to fit into the outer portion of the casing and is seated with the lower end portion on the shoulder 5 described. The bottom bar I 2 of the screen sash is provided with a relatively narrow horizontally extending slot I3 the bottom of which is flush with the outer end portion of the upper ledge board. This slot is widened at the inner end to form a shoulder M to receive a rectangular frame l5 of tin or other suitable material. The latter is folded upon itself at the outer edge so that the cross-section of the frame has the shape of a U opening inwardly or towards the opposite bar of the frame. Screen material I6 is clamped between the legs of the U described and keeps insects out, but does not materially obstruct the flow of water collected on the window ledge. The tin frame gripping the screen material is secured to the lower bar of the screen sash by screws I 1 in countersunk relation. The foregoing description and drawing have reference to what may be considered the preferred or approved form of my invention. It is to be understood that I may make such changes in construction, arrangement and combination of parts, materials, and proportions as may prove expedient and fall within the scope of the appended claims.

What I claim and desire to secure by Letters Patent is:

1. In a window screen drain the combination with a window casing including a ledge of lesser horizontal width than the thickness of the remaining casing and thereby defining a recess for a screen fitted into the casing and seated with its lower end in the recess, a screened opening in the lower board of the screen and having a bottom flush with the top surface of the ledge.

2. In a window screen drain the combination with a window casing including a ledge recessed at its upper and outer corner edge, of a window screen frame fitting into the casing and seated 3 with its lower end portion in said recess, an opening in the lower bar of the screen frame having a lower edge flush with the top surface of the ledge, and a clamping fram in the opening for clamping screen material therein.

3. In a window screen drain the combination with a casing and including a ledge having a recess at the upper and outer longitudinal corner edge, of a screen frame received in the casing and having a lower'loar extendinginto said recess,

an opening in the lower bar of the frame and having a lower edge flush with the top surface of the ledge, a screen holding frame in the opening, said first-mentioned frame being channelshaped in cross-section and arranged to open inwardly, and a. screen clamped by the holding frame and closing the opening in said lower bar to insects.
